74LCX540  
Low Voltage Octal Buffer/Line Driver  
with 5V Tolerant Inputs and Outputs  
General Description  
The LCX540 is an octal buffer/line driver designed to be  
employed as a memory and address driver, clock driver  
and bus oriented transmitter/receiver.  
Features  
■ 5V tolerant inputs and outputs  
■ 2.3V–3.6V VCC specifications provided  
■ 6.5 ns tPD max (VCC 3.3V), 10 A ICC max  
This device is similar in function to the LCX240 while pro-  
viding flow-through architecture (inputs on opposite side  
from outputs). This pinout arrangement makes this device  
especially useful as an output port for microprocessors,  
allowing ease of layout and greater PC board density.  
■ Power down high impedance inputs and outputs  
■ Supports live insertion/withdrawal (Note 1)  
■ Implements patented noise/EMI reduction circuitry  
■ Latch-up performance exceeds JEDEC 78 conditions  
■ ESD performance:  
The LCX540 is designed for low voltage (2.5V or 3.3V) VCC  
applications with capability of interfacing to a 5V signal  
environment. The LCX540 is fabricated with an advanced  
CMOS technology to achieve high speed operation while  
maintaining CMOS low power dissipation.  
Human body model 2000V  
Machine model 200V  
■ Leadless Pb-Free DQFN package  
Note 1: To ensure the high-impedance state during power up or down, OE  
should be tied to V  
through a pull-up resistor: the minimum value or the  
CC  
resistor is determined by the current-sourcing capability of the driver.
